Frame Geometry: Deadcat, Squished X, or True X?

When choosing a frame for your FPV drone, geometry plays a crucial role in determining flight characteristics, aerodynamic efficiency, and how clean your camera footage will be. Among the most popular configurations are Deadcat, Squished X, and True X. Each has distinct advantages and trade-offs, especially in racing, freestyle, and cinematic applications.

True X
All four arms are equidistant from the center, forming a perfect “X” shape. This creates a symmetrical thrust layout.

Pros:
- Equal arm length provides identical pitch and roll response, ideal for racing and acrobatic flying
- Consistent stick response in all directions
- Battery and flight controller typically sit at the center of mass

Cons:
- Propellers in view. The front arms often appear in the FPV or HD camera feed

Squished X
Arms are angled to create a more rectangular X shape, with a shorter front-to-back distance than True X. Common in racing and some freestyle frames.

Pros:
- Faster yaw and pitch rates: Shorter axis allows for quicker flips and rolls
- Enhances maneuverability, especially in tight tracks
- Lower profile. Slightly improved aerodynamics in forward flight

Cons:
- Mild asymmetry. Slightly unbalanced thrust distribution compared to True X
- Partial prop view. Depending on camera angle and frame, front props may still be visible

Deadcat
Front arms are angled outward more than the rear ones, creating a wider front.

Pros:
- No propeller intrusion in camera view. Excellent for cinematic flying and clean HD footage
- Ample space for camera gear: More room at the front for GoPro, ND filters, or gimbals
- Less vibration in footage

Cons:
- Asymmetric motor layout: Imbalanced thrust can slightly affect flight behavior
- Potential CG shift: Uneven distribution may require battery repositioning for balance

For freestyle and racing, True X and Squished X offer better performance due to their symmetrical handling and consistent thrust vectors. Deadcat, on the other hand, is the go-to for cinematic pilots who prioritize clean footage over flight aggressiveness.

Recommendation:

- Choose True X if you value balance and precision in aggressive flying.
- Opt for Squished X if you need a middle ground—nimble response with some camera clearance.
- Go for Deadcat if your priority is filming with no prop intrusion, especially with HD cams like GoPro or DJI O3.

Frame geometry isn't just an aesthetic or structural choice—it's a foundational element of your drone's flight behavior and footage quality.
